Southwest Bancorp 1Q Results: One-Time Cash Receivable Write-Off Reduces Net Income; Effect on Assets and Capital Not Material; Portfolio Loans Grow 20%

     April 24, 2007, Stillwater, Oklahoma . . . . Southwest Bancorp, Inc. (Nasdaq National Market—OKSB), (“Southwest”), today reported net income for the first quarter of 2007 of $4.5 million, a 28% decrease from the $6.3 million reported for the first quarter of 2006. Diluted earnings per share were $0.31 compared to $0.44 per share for the 2006 period, a decrease of 30%. The first quarter results reflect a one-time write-off of the $2.5 million receivable for cash that was in the custody of an armored transportation company. This is the estimated maximum loss related to the receivable, and does not reflect potential recoveries, insurance coverage, or additional expenses of pursuing recoveries. The after tax effect of this write-off was $1.5 million or $0.10 per share. With related legal costs of approximately $300,000, this matter was responsible for a reduction in net income of $1.7 million or $0.12 per share. See “Cash Receivable” discussion below. The write off did not have a material effect on the assets or capital of Southwest or Stillwater National Bank and Trust (“Stillwater National”).

     Rick Green, President and Chief Executive Officer, stated, “The receivable write-off adversely affected the bottom line for the quarter. But we also had good news. At quarter end, portfolio loans were almost $1.7 billion, up by 20% over first quarter 2006, and 4% over last year-end. The increases in portfolio loans are the direct result of our geographic growth strategy. At March 31, 2007, our Texas and Kansas operations accounted for $777 million, almost half of total portfolio loans.”

Highlights

•   Portfolio loans:	$1.7 billion, a 4% increase from year-end 2006 and a 20% increase from first quarter 2006
•   First quarter net income:	$4.5 million, a 28% decrease from first quarter 2006
•   Return on average equity:	9.04% for the first quarter 2007

(Please see Financial Tables 1 through 6 for additional financial information.)

Results of Operations

     The $1.8 million, or 28%, decrease in quarterly net income from the first quarter 2006 was the result of a $3.6 million (28%) increase in other expense and a $628,000 (16%) decrease in other income, offset in part by a $472,000 (2%) increase in net interest income, an $815,000 (30%) decrease in provision for loan losses, and a $1.2 million (30%) decrease in income taxes. Net income for the quarter included the effects of the $2.5 million write-off, approximately $300,000 in related legal expenses, and a $450,000 investment impairment charge reflected in securities losses.

     The $472,000 increase in net interest income for the quarter was primarily the result of increased loan yields. Although the provision for loan losses decreased, the allowance for loan losses increased to 1.56% of total loans at quarter end, up from 1.52% at December 31, 2006. The decrease in other income was mainly the result of a

Southwest Bancorp 1Q Results

$569,000 decrease in service charges mainly due to the decrease in the number of ATMs owned by Cash Source, Inc. (“CSI”), a subsidiary of Stillwater National, a $185,000 increase in net securities losses, mostly due to the $450,000 investment impairment charge, and a $207,000 decline in other noninterest income, offset in part by a $303,000 increase in gains on sales of loans. The decline in ATM charges related to reduced operations of CSI. (See “Cash Receivable,” below.) Although CSI’s ATM fees decreased in the first quarter, CSI did not produce a significant contribution to net income in the first quarter 2006 or the year ended December 31, 2006, and the reduction in its owned ATMs will not have a significant effect on future net income.

Financial Condition

     At March 31, 2007, total assets were $2.2 billion, a $23.6 million, or 1% increase from year-end 2006. Shareholders’ equity at March 31, 2007 totaled $201.8 million, a $4.3 million, or 2%, increase from December 31, 2006. Core deposits grew by $39.6 million, or 4%, since year end 2006. Consistent with our previous disclosures, student lending balances have decreased by $79.6 million from year-end 2006 and are expected to continue to decrease.

     Portfolio loans increased by $64.5 million, or 4%, during the first three months of 2007. Portfolio loans increased by $275.4 million, or 20%, from the first quarter 2006. Portfolio loans exclude loans held for sale, almost of all of which are student loans. Southwest’s growth in portfolio loans more than offset the expected reduction in loans held for sale.

     Southwest’s Texas and Kansas offices were responsible for an $86.8 million increase in total portfolio loans for the first quarter of 2007. At March 31, 2007, Southwest’s seven Texas and two Kansas offices accounted for $776.7 million in loans, or 47% of total portfolio loans, up from 43% at year-end 2006. Southwest added two experienced lenders in the first quarter to support the Texas growth strategy.

     Southwest’s Oklahoma offices were responsible for a $22.4 million decrease in total portfolio loans for the first quarter of 2007. Texas and Kansas offices more than offset this decrease, driving the increase in total portfolio loans.

     At March 31, 2007, the allowance for loan losses was $27.7 million, an increase of $435,000, or 2%, from the allowance for loan losses at December 31, 2006. This change is a result of growth in performing commercial and commercial real estate loans and an increase in the historical loss rate on performing secured commercial loans, offset in part by a decrease in the allowances on impaired loans and reductions in the allowance related to potential problem loans. At March 31, 2007, the allowance for loan losses was 1.56% of total loans, compared to 1.52% at year-end 2006. The unallocated allowance at March 31, 2007 was $2.3 million, or 8% of the total allowance. Management believes the amount of the allowance is appropriate, given its systematic methodology of calculation. Changes in the amount of the allowance resulted from the application of that methodology, which is designed to estimate inherent losses on total loans in the portfolio, including those on nonperforming loans.

     The reserve for unfunded loan commitments was $1.9 million at March 31, 2007 and at December 31, 2006.

     Other real estate at March 31, 2007 was $1.9 million, approximately the same balance as year-end 2006. Total nonperforming assets at March 31, 2007 were $31.3 million compared to $31.2 million at December 31, 2006.

     Nonaccrual loans totaled $27.0 million at March 31, 2007 compared to $26.7 million at December 31, 2006. Total nonperforming loans of $29.4 million increased $83,000 from year-end 2006 and represented 1.66% of total loans, compared to 1.64% at year-end 2006. At March 31, 2007, $1.4 million, or 5%, of loans classified as nonperforming were guaranteed by United States agencies or U.S. government sponsored entities.

     Performing loans considered potential problem loans, loans which are not included in the past due, nonaccrual, or restructured categories, but for which known information about possible credit problems cause management to be uncertain as to the ability of the borrowers to comply with the present loan repayment terms, amounted to approximately $52.3 million at March 31, 2007, compared to $50.6 million at December 31, 2006, a 3% increase.

Cash Receivable

     As previously disclosed, in December 2006, an armored transportation company failed to deliver to Stillwater National approximately $1.3 million in cash then due to it from certain ATMs owned by CSI. CSI discovered other cash shortages arising from the same company and Stillwater National has removed all cash from the other CSI

Southwest Bancorp 1Q Results

ATMs for which that company provided cash transportation. Earlier this year, Southwest estimated the maximum total potential loss from these cash shortages as $2.5 million, but was unable to reasonably estimate the actual loss.

     Stillwater National and CSI have filed legal action for the recovery of their funds, have notified law enforcement and bank regulatory authorities and their insurers, and continue to investigate the possible locations of the missing cash and other means of recovery, including the extent of insurance coverage. As a result of its continuing investigations including a continuing analysis of the custodian’s records, which were first obtained in March 2007, Southwest has estimated the loss as the total amount of the receivable, and has recorded a complete write-off of that amount as reflected in the financial statements for the first quarter of 2007. The financial statements also reflect related legal expenses incurred by Southwest in the first quarter of approximately $300,000. Southwest continues to vigorously pursue its investigation and efforts to recover the missing cash or otherwise mitigate its damages. Southwest is in the process of preparing its claim for insurance, which it intends to file in the second or early third quarter of 2007.
